Stabilization Of FeCo Alloy Phase In FeCo-SiO2 nanocomposites

Hardeep Kumar; L. Olivi;G. Aquilanti; S. Ghosh; P. Srivastava; D. Kabiraj; D. K. Avasthi

Volume 4, Issue 6 , June 2013, , Pages 390-397

http://dx.doi.org/10.5185/amlett.2012.ib.101

Abstract
  A series of FeCo-SiO2 granular films of different FeCo atomic concentration (33-54%) have been prepared by fast atom beam sputtering technique and post-annealed in inert (Ar) and reducing (H2) gas environments. Fe and Co K-edge XANES analysis of as-deposited films indicate that both Fe and Co are present ...  Read More

http://dx.doi.org/10.5185/amlett.2012.ib.104

Abstract
  Thin metal films of Ag (~10 nm) deposited on spin coated PVC film on quartz substrate, were irradiated with 150 keV Ar ions at fluences varying from 5×10 15 to 5×10 16 ions/cm 2 and characterized with Rutherford backscattering spectrometry (RBS), atomic force microscopy (AFM), scanning electron ...  Read More

Synthesis Of Carbon Nanowires By SHI Irradiation Of Fullerene C70 thin Film 

R. Singhal; A. Tripathi; D. K. Avasthi

Volume 4, Issue 6 , June 2013, , Pages 413-417

http://dx.doi.org/10.5185/amlett.2012.ib.105

Abstract
  Electrically conducting carbon nanowires, all parallel to each other and embedded in fullerene C70 matrix are created by swift heavy ion irradiation of thin fullerene C70 film at low fluences (up to 10 10 ions/cm 2 ). The conductivity of the wires is several orders of magnitude higher than the surrounding ...  Read More

Tailoring The Size Of Gold Nanoparticles By Electron Beam Inside Transmission Electron Microscope

Y. K. Mishra; S. Mohapatra; D. K. Avasthi; N. P. Lalla; Ajay Gupta

Volume 1, Issue 2 , September 2010, , Pages 151-155

http://dx.doi.org/10.5185/amlett.2010.4116

Abstract
  Au nanoparticles (NPs) embedded in silica matrix were synthesized by atom beam co-sputtering and investigated in detail by transmission electron microscopy (TEM). A study on electron beam induced tailoring of size of Au nanoparticles has been performed in an in-situ TEM experiment as a function of electron ...  Read More
